At present, with the continuous development of 5G applications, the traffic of Network Controlled Interactive Services (NCIS) is introduced into the standard as a new traffic form for performing related standardized traffic. NCIS traffic mainly corresponds to applications such as AR/VR and games, and there are high demands on traffic quality such as speed, time delay, packet loss rate, and high-speed encoding and decoding. For example, if it is a VR game, it must reach 10Gbps speed, and the packet loss rate must not exceed 10E-4. A session established for NCIS traffic is an NCIS session, and UEs in the same NCIS session may be considered to form a team in one NCIS group, for example, a game. The UE in the NCIS group has the following possible communication methods and can be used in combination.

- When they are close to each other, for example, broadcast or multicast is performed using D2D technology, or one-to-one communication (unicast) is performed by establishing a sidelink (also called using a PC5 interface).

- If they are far away from each other, use, for example, UE-network-server-peer network-peer UE (also called using Uu interface).

UEs in a group may come from the same Public Land Mobile Network (PLMN), or from different PLMNs. For example, there are 5 UEs in one NCIS group, 3 of which are UEs with PLMN 1, 2 UEs with PLMN 2, and 3 UEs with PLMN 1 in PC5 interface using D2D technology. They can communicate directly with each other, and at the same time also communicate using the network with two PLMN 2 UEs.

The architecture of the UE-to-network relay system is a UE-to-network relay, which is a relay from the user device to the network, as shown in FIG. 1d , and serves the communication of the remote UE, where SGI is the core network and packet data As an interface between network (Packet Data Network, PDN) gateways, the architecture can provide faster and more reliable services.

A flow diagram presenting a relay transmission initiation signaling interaction as shown in FIG. 1E includes the following steps.

Step 1: Network-side initial attachment and/or relay UE requests PDN connection, E-UTRAN initial attachment and/or UE requests PDN connection (E-UTRAN Initial Attach and/or UE requested PDN connectivity).

Step 2: The relay device and the remote device complete the Discovery Procedure.

Step 3: The relay device completes the establishment of connection For one-to-one communication with the remote device.

Optional step 3: The relay device may complete Relay UE may establish a new PDN connection for Relay.

Step 4: The remote device reports IP address/prefix allocation to the relay device.

Step 5: The remote device reports the remote device report (remote user identifier, IP address information) (Remote UE Report (Remote User ID, IP info)) to the network side.

Step 6: The network-side entity delivers a remote device report (remote user identifier, IP address information) (Remote UE Report (Remote User ID, IP info)).

In the above process, the relay UE of option step 3 needs to use an appropriate PDN connection in order to transmit the relay data of the remote UE. Which PDN connection is used to transmit relay data is determined by the relay UE, and in general, the relay UE can transmit all relay data using a dedicated PDN connection. In the 5G architecture, the relay UE establishes an appropriate PDU session to transmit data of the remote UE. The uplink data is the direction of the remote UE-»relay UE-»RAN-»5GC-»DNN-»application server. The downlink is in the reverse direction.

QoS that transmits data both in the PDU session of the PC5 connection and relay UE in order to provide better service to the remote UE and to satisfy different traffic requirements, such as transmission speed, time delay, packet loss rate, etc. There is flow. Different QoS flows support different QoS requirements. How the relay UE matches the QoS flow of the PC5 connection with the QoS flow of the PDU session is a problem to be solved.

In response to the above problem, the embodiment of the present application proposes a QoS parameter configuration method, which will be described in detail with reference to the accompanying drawings below.

Referring to FIG. 2A, FIG. 2A is a diagram illustrating a flow of a QoS parameter configuration method provided by an embodiment of the present application. As shown in the figure, the method includes the following.

Step 2a01: The network device sends a mapping relationship between the first QoS parameter and the second QoS parameter. The first QoS parameter is applied to a first QoS flow, and the second QoS parameter is applied to a second QoS flow. The first QoS flow is a QoS flow between the first device and the network device, and the second QoS flow is a QoS flow between the first device and the second device.

Here, the mapping relationship can be described as PC5 QoS-Uu QoS mapping in the protocol.

In a specific implementation, the network device transmits the mapping relationship to all UEs supporting 5G Proximity Service (ProSe), or transmits the mapping relationship only to UEs that can be relay UEs, or a local terminal receives The mapping relationship may be transmitted to a designated relay UE according to an identifier of one relay UE and/or a remote UE, but the mapping relationship is not limited thereto.

Step 2a02: The first device acquires a mapping relationship between the first QoS parameter and the second QoS parameter. The first QoS parameter is applied to a first QoS flow, and the second QoS parameter is applied to a second QoS flow. The first QoS flow is a QoS flow between the first device and a network device, and the second QoS flow is a QoS flow between the first device and the second device.

In the embodiment of the present application, the first device may know that the second device is a relay device accessing the network device.

The first QoS parameter is applied to the first QoS flow, the second QoS parameter is applied to the second QoS flow, the first QoS flow is a QoS flow between the first device and the network device, and the second QoS flow is the first QoS flow. Since it is a QoS flow between the device and the second device, the first device uses the correct QoS flow according to the above-described mapping relationship to relay the data sent by the second device to the network device, or the network device to the second device It is possible to relay the transmitted data, thereby providing a better service guarantee to the second device.

In one possible embodiment, the first QoS parameter comprises a fifth generation 5G traffic quality index (5QI) and the second QoS parameter comprises a PC5 quality of service index (PQI).

For example, a possible form of the PC5 QoS-Uu QoS mapping is a mapping of 5QI and PQI. For example, 5QI 1 corresponds to PQI 21.

In a specific implementation, the format of the PC5 QoS-Uu QoS mapping may be as shown in Table 1. Here, PC5 Uu quality of service mapping (QoS mapping) information element identifier (Information Element Identifier, IEI) is PC5 Uu QoS mapping length (Length of PC5 Uu QoS mapping) indication area, idle bit (Spare), QoS flow index (QoS flow) Index, abbreviated QFI) indication area, may include a mapped PC5 quality of service index (Mapped PQI) indication area. Here, QFI corresponds to 5QI, that is, corresponds to a QoS flow (also referred to as a first QoS flow or Uu QoS flow) between the first device and the network device.

In this example, the mapping relationship between the first QoS parameter and the second QoS parameter can be accurately indicated through the mapping of 5QI and PQI, so it can be seen that the data volume is small and the transmission efficiency is high.

In one possible embodiment, the first QoS parameter comprises an identifier of the first QoS flow, the second QoS parameter comprises an identifier of the second QoS flow, wherein the identifier comprises an identity identifier (ID) or index (Index).

In a specific implementation, the format of the PC5 QoS-Uu QoS mapping is as shown in Table 2, where the PC5 Uu QoS mapping information element identifier (IEI) is a PC5 Uu QoS mapping length indication area (Length of PC5 Uu QoS mapping), It may include an idle bit, an indication area of the first QoS flow identifier, and an indication area of the second QoS flow identifier.

Table 2

In this example, the mapping relationship between the first QoS parameter and the second QoS parameter can be accurately indicated through the identifier of the QoS flow, so it can be seen that the data volume is small and the transmission efficiency is high.
